I can't determine how to change my avatar and what size photo I should use. What are the dimensions? XxY?
Is there a post minimum?
-----edit------------------
This is how I determine the size of an acceptable avatar, brute force method:
1. screenshot of a post with an avatar/userpic.
2. Paste into MS graphics program
3. Determine the size displayed on the screen, the X x Y dimensions I requested.
then
4. create an avatar with THOSE SPECIFIC dimensions.
